Definitely reads as a mech. Sort of has an "Urbanmech trying to peek over a building" vibe. The feet are particularly clever, as you get a really wide range of motion out of that simple connection.
Last mention and then I'll get off the MFZ diversion, but you also don't have to use Lego. That was the original inspiration and it works for peeling off systems as you take damage, but you can make frames out of anything (even binder clips, rubber bands, and post-its)
. It's just convenient to make it a visual representation of the frame's stats (and tear it apart as it loses stats due to damage) and some people happen to enjoy making tiny robots.
With that being said, here are some more tiny robots to stay on topic. These were a part of a challenge to design a frame using only 6 different parts. I really wanted to try these out with the Rooftop Racing rules
but never quite got around to it.
